HULLlNG-MACHINE.

SPECIFICATION forming part of Letters 'Patent No. 746,881, datedDecember 15, 1903.

Application filed April 14, 1902. Serial No. 1025863. (No model.)

To (LZZ- whom, it concern:

Be it known that I, FRED N. ROOT, a citizen of the United States,residing at Kalamazoo, in the county of Kalamazoo and -State ofMichigan, have invented certain new and useful Improvements inHulling-llachines, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention has reference generally to an improved type of mechanismfor hulling peas, beans, or like seeds; and it consists in the novelconstruction of said mechanism whereby the hulls may be rapidly andeffectively removed from the kernels in a minimum space of time.

The invention further consists in the peculiar arrangement andcombination of the va rions parts of the hulling mechanism, as will bemore fully hereinafter described, and shown in the drawings, in which-Figure l is a side elevation of the hullingmachine, partly-in section.Fig. 2 is a section taken on line 2 2 of Fig. l. Fig. 3 is a plan view,and Fig. 4 is a sectional perspective view, of one of the movablemembers.

In the drawings thus briefly described the reference-letter A designatesthe base-section of the machine. 'B B are standards thereon at theopposite -ends of the base, upon which is mounted the mainoperating-shaft C, journaled for rotary movement in bearings UCC C"designates means in the form of drivepllilleys for imparting rotarymovement to the s a t.

The letter D represents one of the movable hulling members of myimproved machine, between which and the complementary movable member K/the kernels are adapted to be fed, the hulls being separated from thekernels during their passage between the members, as hereinafter setforth'. In construction the member D is in the formpof a disk fixed tothe main shaft, as shown, and having a rubbing-surface D', consistingof, preferably, a layer of rubber or felt upon one of its faces.

The complementary movable member referred to I have shown in the form ofan endless carrier extending in operative relation to therubbing-surface upon the disk. The carrier is adapted to feed thekernels uniformly and comprises a belt K, which may be an ordinarycanvasbelt, passing over a roller E at one end and rollers I' I' at theopposite end. These latter rollers, as shown, are mounted uponhorizontal shafts I I, arranged one above the other in adjacence to thedisk and mounted in suitable bearings upon standards -H upon the base.

J designates a trough mounted upon standards M upon the base, throughwhich the upper portion ofthe carrier K passes, as plainly shown inFig. 1. The trough extends at one end in close proximity to the rollersl/ I and at its opposite end is provided with a hopper J', through whichthe kernels are fed to the carrier.

Motion is im parted to the carrier through the agencyof the shaft E,journaled in bearings F' upon standards F, a bevel gear-wheel G uponsaid shaft, and a gear-pinion G upon ythe main operating-shaft O,thedriving mechanism described being adapted to operate the carrier at aless speed than the disk.

In operation the beans or other kernels that are to be hulled are firstsoaked,so as to loosen the hulls, and are then fed through the hopperonto the carrier. From thence they pass betweenvthe end of the carrierdescribed and the rubbing-surface upon the disk. Y It will be obviousfrom the construction of the in echanism as set forth that in additionto the rubbing the. kernels will receive due to the nnequalA velocitiesat which the two movable members are moving a twisting movement willalso be produced due to the fact that the rubbing-surface upon the disktravels at different velocities at dierent distances from its axis ofmovement. The hulls are therefore rapidly and effectively removed fromthe kernels and are discharged from between the complementary surfacesinto a spout J. The separation of the hulls from the kernels maybesubsequently effected by any suitable mechanism. As there is a tendencyfor the hulls to adhere to the surfaces ofthe movable members, I may andpreferably do ein ploy means for keeping said surfaces cleansed. Ipreferably accomplish this l by discharging water within the trough Jthrough the pipe L, controlled by a suitable valve L. The

Y. essary that both of the members should be movable. This will bereadily apparent from the construction of the mechanism asset forth.

What I claim as my invention isl. In a hulling-machine, the combinationwith two complementary hulling members, comprising a rotary disk, and anelongated endless-belt carrier extending transversely to the disk, ofrollers bearing against the inner surface of the t'op and bottom of theend of the belt adjacent the disk for guiding the said end portion ofthe belt across the surface of the face of the disk.

2. In a hulling-machine, the combination with two complementary hullingmembers, comprising a vertically-rotating disk, and an endless beltextending transversely to the disk, of means for operating the members,and means contacting the inner surface of the belt for guiding a portionof the outer surface thereof across the face of the rotary disk.

In testimony whereof I affix my signature in presence 'of two witnesses.

FRED N. ROOT.
